THOMAS H. KERINS, OF SOUTH SHARON, PENNSYLVANIA.

TOBACCO-PIPE.

To all whom it may concern:

Be it known that I, THOMAS H. KERINs, a citizen of the United States,residing at South Sharon, in the county of Mercer and State ofPennsylvania, have invented certain new and useful Improvements inTobacco- Pipes, of which the following is a specification, referencebeing had to the accompanying drawings.

My invention relates to improvements in tobacco smoking pipes and moreparticularly those having means for collecting saliva and nicotin.

One object of the invention is to provide a pipe of this character whichwill be simple and inexpensive in construction and effective inaccomplishing its intended purpose.

Another object of the invention is to provide a nicotin and salivacollecting device in the form of an attachment which may be readilyapplied to pipes of ordinary construct-ion.

With the above and other objects in view, the invention consists of thenovel features of construction and the combination and arrangement ofparts hereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which Figure 1 is a side elevation of a pipehaving my invention applied thereto; Fig. 2 is a longitudinal sectionthrough the same; and Fig. 3 is a similar sectional view showing amodified form of the invention.

In the drawings 1 denotes a pipe of well known construction having atobacco cavity or bowl 2 and a communicating smoke passage or bore 3 inits stem a. The latter may have a mouthpiece 5 of any form andconstruction.

In the practice of my invention I form in the bottom of the stem at, ata point in rear of the bowl, a socket or cavity 6 which communicateswith the smoke passage 3 at a point adjacent to the bottom of thetobacco bowl 2 and which is adapted to receive a removable cup-shapedplug 7. The cavity 6 and the plug 7 form a collecting chamber fOr salivapassing down through the smoke passage 3 and for the nicotin andparticles of tobacco, which pass from the bowl 2 through a short channelorpassage 8 formed in the rear portion of the base of the bowl into theupper portion of the cavity. By arranging the cavity or chamber 6 asillustrated, it will be seen that the smoke in passing through thepassage 3 must pass over Specification of Letters Patent.

the top of said cavity so that any particles of solid matter and nicotinwill drop down into said chamber and lodge in the hollow or cavity 9 inthe plug 7. The disposition of the chamber 6 in the stem immediately inrear of the bowl 2 does not in any way interfere with the properoperation of the pipe and there will be no danger of the tobacco in thebowl clogging up'said chamber. Said cavity or chamber 6 may be readilyformed by boring a hole at the proper point in the stem 4 and of theproper size to receive the plug 7 The latter may be in the form of aplain cylinder and retained in the cavity 6 by friction, as shown inFig. 3 of the drawings, or the lower portion of the cavity 6 may bescrew threaded and the outer surface of the plug 7 may be similarlythreaded, as shown at 10, and screwed into said cavity, as illustratedin Fig. 2. The bottom of the plug is formed in both cases with anannular radially projecting flange 11 the outer edge of which ismilled,as shown in Fig. 1, so that the plug may be readily turned in applyingit to or removing it from the pipe. It will be observed that the passage3 inclines upwardly and rearwardly at an oblique angle from the upperrear portion of the cavity 6, while the passage 8 inclines downwardlyand rearwardly at an oblique angle from the lower rear portion of thebowl and connects the same with the upper front portion of the cavity 6.By this construction a dam or deflecting surface 6 is formed by theupper portion of the rear wall of the cavity between the plug 7 andpassage 3, and the smoke discharging from the bowl through the passage 8takes a downward course and strikes against the edge of the plug andalso against said dam or deflecting surface 6 before'entering thepassage 3. As a result, the smoke is retained or retarded momentarily inthe cavity and any particles of nicotin-laden saliva passing out with itare deposited to a large extent on the rim edge of the cup and on thedam or deflecting surface and to a lesser extent on the remainingsurfaces of the walls of the cavity and trickles down into the plug,thus facilitating and increasing the separation of the nicotin andsaliva from the smoke and the deposit of the same in the From theforegoing it will be seen that my invention provides an exceedinglysimple and inexpensive means for collecting the Patented Aug. 24, 1909.

nicotin and saliva in a pipe and one which will not interfere with theordinary operation of the pipe and which permits the pipe to be easilycleaned. The invention may be applied to a pipe when it is being made,or

it may be applied by anyone by simply bor I claim is:

1. A tobacco pipe comprising a body of conventional shape and formedwith directly connected integral bowl and stem portions, the formerbeing provided with a tobacco well and a channel leading from the lowerrear portion thereof and the latter having a smoke passage, said bodyalso being provided in its bottom in rear of the well and between saidwell and its point of junction with the base ofthe stem with a verticalcavity arranged below the rear wall of the bowl and communicating at itsupper end with said channel and passage, and a hollow cup-shaped plugremovably fitted in said cavity and having an open upper end and aclosed lower end formed with an annular rim flange, the said upper openend of the plug terminating below the upper end of the cavity and alsobelow said channel and passage.

2. The herein-described improved tobacco pipe comprising a body ofconventional shape and formed with directly connected integral bowl andstem portions, said bowl portion being provided with a tobacco wellhaving a channel leading at an outward and downward angle from the lowerrear portion thereof, and said stem portion having an upwardly andrearwardly inclined smoke passage, the said body being also provided inits bottom in rear of the well and at the 'junction of the bowl with thestem with a vertical cavity arranged immediately below the rear wall ofthe bowland intersecting and separating said channel and smoke passage,and a hollow cup-shaped plug removably fitted in said cavity and havingan open upper end and a closed lower end, the latter provided with anannular rim flange, the upper rim edge of said plug terminating belowthe top of said cavity and below'the said channel and passage, theangular arrangement of the channel causing the smoke to flow downwardagainst the rim edge of the plug before discharging through the passageand the upper rear portion of the wall of the cavity forming a verticaldeflecting surface between said rim edge and passage to facilitate theretention and deposit of the saliva and impurities within the cavity andplug, substantially as described.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
